[SM] It is not, but that's on me for not having any previous knowledge of a landform called Lord Hereford's Knob. [b] It...certainly protrudes from it, but no, more localised than that.
[blamelewis] Aye! It is indeed Arthur’s Seat. Take these bagpipes and a sturdy pair of hiking boots, and either play to the wind or chuck them off the top, I guess.
[Tuj] Not aware of any of them going by Arthur. [Raak] Not an individual. [Projoy] 25 more guesses. [Simons] Possibly, but it's not a regular part of the human diet. Also lots of people would be quite cross.
